Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed August 16, 1906. Serial No. 330,786.

To (all 111700111, it may concern:

Be it known that I, STANLEY HAYES, a citizen of the United States, and a resident of Geneva, in the coxnty of Ontario and State of New York, have invented certain new and useful Improvements in Derailers, of which the following is a hill and concise specification.

My invention relates to derailers, and more especially to a means of mounting and. giiiding the movable wheel-derailing member thereof iipon the base member, whereby the reciprocation of the derailing member by a suitable connection at its rear end will cause a lifting or r1p-and-over movement of the derail-block at the other end.

The invention also involves the relative arrangement of the parts for effecting the above motion and the arrangement of the locking means, all as will be fully described and herein claimed.

In the accompanying drawings, forming a part hereof, Figure 1 is a plan view of a derailer, with the derailing member in an intermediate or half-way position, constructed in accordance with my invention and with half of the base member thereof broken away. Fig. 2 is a vertical transverse section of Fig. 1 on line H 11. Figs. 3 and 4 are side elevations with base in section and derailing member respectively in closed and open p0sitions. Fig. 5 is a rear elevation with a central operating or locking connection. Fig. 6 is a detail in section of said central connection, and Fig. 7 is a side elevation of the device of Fig. 5 with the central connection reversed.

The base member of the device above illustrated is comprised of a single casting, which is formed with two side walls 1 1, baseflanges 2 2, snitably reinforced by integral angle-braces 2, and a cross-piece 3, joining the two walls at the top. ()11 the rndcr sides of the baseflanges are two parallel tieflanges 4 4, which are adapted to engage and space the edges of two adjacent tics when the member is installed on the road-bed so as to anchor the apparatus firmly thereto. The forward portion of the base is slightly elevated and extends above the base-flange ofthe rail, forming a seat or pocket 5, which is adapted to receive a corresponding part of the derailing member when it is in its operative or active position to sustain it against movement parallel with the rail. The portion of the base member in the rear of the i cross-piece 3 is formed as a slideway.

Tne wheel-derailing 111.011:l)01' 001111011568 a derail-block 6 of ordinary formation, carried by a derail-block arm 7, which is mounted io reciprocate within the chaniber fornicd by the walls of the base nicnlber. At its forward or derail-block end the arm 7 is carried by a rocking link 8, which is pivoted to the base by naears of the cross-pin 9, the latter being supported in the base by the tie-llangcs or by the lugs 10, which constitute parts of said llangcs. The upper end of the link occupies a straight-sided groove or recrss formed in the under side of the derail-block arm and is pivoted therein by met is of the pin 11, secured in the side walls of the arm. The rear end of the derail-block arm is adapted to slide in the rear ponion of the base in a substantially straight direction toward and irom the rail, and to this end it is provided with lateral lugs 12, which rest on the inwardly-projecting flanges 13 of the base, the latter iorniing the slideway. However, the lugs can be formed on the base to engage groovcs in the sides of the arnis with equal effect. The lugs are round, so as to permit the lifting movement of the derail-bio ck. The means whereby the above device may be operated and also looked in position (in interlocking plants) are applied d ii cctly to the (lei-ailing member at the extremity of the arm 7 and coniipiise two connection-lugs 15 and 15, which are formed as integral extensions of the side walls of the itlll'S and depend therefrom i o a point below the lugs and slidcway, and preferably below the level of the cross-pin 9. One or both of these lugs may be used, desired. The opcrating-jaw 14 is pivoted to the end of the lug by a pin or bolt. hen one of the lugs is thus employed for operating, the other may be employed for the locking means, and a second conncciiou means, p1 rscnily to be de scribed, may also be O11.])l() Y((l. In Figs. 6 and 7 the lug 15 is connected with a llat bar 17, which is a part of an ordinary facingpoint lock not requiring description. \Vhen the dera iling niember is ntoved to either position, this device servrs to lock it in place in well-understood manner. The second locking means, or it may be a signal-operating means or a secondary operating means, is intended to be connected directly to the derailing men her by bring pinned to the connection-head 18 of a bolt 19, which is set into the cross-flanges 7 of arm 7, occupying a central position with respect to-the lugs 15 and 15 and being also somewhat below the slideway, Figs. 5 and 6. This bolt is reversible, so that the perforated connection-head 18 can be placed under the arm 7, where it can be more conveniently operated by a connection coiring from an opposite direction, as clearly indicated in Fig. 7. One or more of these connections may be employed, according to requirements.

The link 8 is so pivoted with respect to the horizontal traverse of the derailing member that when the latter is withdrawn from the rail it occupies the inclined position, not quite horizontal, which is indicated iii-Fig. 3, the derail-block in this position being depressed but when the derailing member is pushed forward by the operating connection above mentioned the direction of the operating force is such that the link is lifted by the pressure on the arm and rocked forward to the inclined position shown by Fig. 4. In swinging forward the link imparts a rising or up-and-over movement to the derail-block, which movement serves to place it properly upon the rail. The action is of course the reverse in withdrawal. The linkis of massive proportions relative to the rest of the apparatus and fits rather snugly within the recess of the arm, so that it is specially suited to guide and steady the derail-block during its movement and also to aid in resisting the severe strains of derailing, and in swinging over its point of unstable equilibrium it lends its own considerable weight to that of the other moving parts, so that the derailing member is carried with a free and easy swing to the extreme end of its traverse in either direction that is to say, the center of gravity of the heavy link is mounted so that it must pass over its point of pivotal support, and therefore requires only to be lifted during the beginning of the stroke to its point of unstable equilibrium, whereupon it moves by gravity the rest of the stroke, and thereby effects a full and complete throw with the minimum of exertion, it being a most desirable point in track appliances of this kind that the moving parts are readily and freely moved, especially during the latter part of their strokes.

In its closed position the derail-block rests upon the side walls of the base and in this position maintains the link in the inclined position shown in Fig. 3, keeping it from dropping below deadcenter. By attaching the operating connection 14 to the end of the connection-lug, which thus becomes a crankarm, the force applied in pushing the derailing member toward the rail becomes resolved partly into a rotary force, which tends to turn the derail-block arm on the lugs 12 as a center, and therefore helps in raising and throwing the link forward over its pivot-pin 9, all of which is important in facilitating the action of the mechanism, as is plain to those skilled in the art.

In order that the derail-block may assume its depressed position resting on the walls of the base, recesses 16 are formed in its sides to accommodate the cross-pin 9, as indicated in the drawings.

Having described my invention, what I claim, and desire to secure by United States Letters Patent, is-
